> The people refusing shelter are refusing to throw away all of their remaining possessions for the promise of a few nights inside and then getting kicked out.
That's true for some. But there are many who would not accept a guaranteed permanent shelter bed because they prefer the freedom of living on their own. If you won't accept the reality of that, you'll never solve the problem.
The solution is likely the same here as it is elsewhere: not a permanent shelter bed where you are stripped of dignity and any facsimile of a normal life, but real homes and real independent lives surrounded by real people and the social connections that make permanent escape from poverty possible. And all of it, ideally, before destitution rather than after. But that's expensive, so we will continue to see handwringing about the deplorable plight of the homeless while the glittering lives of the wealthy grow ever more gilded.
Those shelters are only useful for sleeping (that's the only thing they were optimized for). The people that go there still don't have a place to call home. During the day the homeless go outside and will cause all the same issues that come with regular homelessness.
